An Operating system is a piece of software that controls a computer.What are some of it's characteristics ?
  • it manages hardware and applications
  • diagnoses problems with applications and hardware
  • stores, retrieves and manipulates files
  • manages the BIOS and memory
What is the current listing of Operating Systems available.
  • DOS (Disk Operating System) Windows 9x Windows NT
  • Windows 2000 Windows ME Windows XP Windows Vista Windows 7 Mac OS UNIX Linux
This acts as the interface (or GUI if you will) between the human and the machine.
The Shell acts as the interface (or GUI if you will) between the human and the machine.
This is the primary area of the PC that deals with interacting with the hardware.
The Kernel is the primary area of the PC that deals with interacting with the hardware.
This acts as a database of all application and hardware settings stored for a specified user in a Windows Operating Environment.
The Registry acts as a database of all application and hardware settings stored for a specified user in a Windows Operating Environment.
INI or INF files are specified files that store specific settings on a specified program in order for it to run a certain way.
INI / INF files are specified files that store specific settings on a specified program in order for it to run a certain way.
___________ processes data in 16 bit intervals. The application has complete control over all hardware resources, which can create conflicts when more than one application is using the same hardware resource.
Real Mode processes data in 16 bit intervals. The application has complete control over all hardware resources, which can create conflicts when more than one application is using the same hardware resource.
(Processors) operate in 32-bit mode.
Pentium Processors operate in 32-bit mode.
Software written for Windows 3.x is called 16-bit Windows Software. Data access is 16 bits at a time, but unlike most Protected Mode software,
Software written for Windows 3.x is called 16-bit Windows Software. Data access is 16 bits at a time, but unlike most Protected Mode software, it has code written to enable it so that each program does not infringe upon the resources being used by another program written at the same time.
_____________ is the the 32 bit data flavor of this series.
Protected Mode is the the 32 bit data flavor of this series.
__________________________ all use 32 bit mode.
Windows 9x / ME / NT / 2000 / XP all use 32 bit mode.
The____________, ____________, and the _________ processors all support the long 64-bit mode.
The Intel Itanium, AMD Opteron, and the AMD Athlon 64 processors all support the long 64-bit mode.
In Protected and Long Mode the Operating System is responsible for control of hardware resources ,using a method known as _____________________.
In Protected and Long Mode the Operating System is responsible for control of hardware resources ,using a method known as preemptive multitasking.
Preemptive multitasking involves ?.
Preemptive multitasking involves allowing each application an alloted time on the CPU before the next application borrows the CPU processing power and so on, and so on, acting as a looping cycle.
Each mode has it's own version of hardware ___________.
Each mode has it's own version of hardware drivers as well. There are 16-bit mode Drivers, 32-Bit mode Drivers, and 64-bit mode Drivers.
